The LymphoPro Feline Dx™ test, patent pending, was developed in collaboration with Jörg M. Steiner and Sina Marsilio. The goal of this research partnership was to develop a diagnostic test that differentiates between feline small cell lymphoma (SCL) and inflammatory bowel disease (IBD). Felines suffering from either condition can present with similar chronic gastrointestinal symptoms. Differentiating between these two conditions can be challenging for veterinary specialists, as histopathology often proves inconclusive, and currently available tests, such as immunohistochemistry (IHC) and PCR for Antigen Receptor Rearrangements (PARR) testing, do not deliver high sensitivity and specificity. LymphoPro Feline Dx is intended to help veterinarians render a more accurate diagnosis and provide the following benefits as compared to currently available tests:

arrow-small-green Improved accuracy
arrow-small-green Objective classifications
arrow-small-green Faster results turnaround
arrow-small-green Less tissue required 



Professor, Small Animal Internal Medicine
Texas A&M University

Jörg Steiner received his veterinary degree from the Ludwig-Maximilians University in Munich, Germany in 1992. He completed an internship in small animal medicine and surgery at the University of Pennsylvania in 1993 and a residency in small animal internal medicine at Purdue University in 1996. He received his degree from the Ludwig-Maximilians University in Munich, Germany in 1995 in recognition of research on feline trypsin and feline trypsin-like immunoreactivity. In 1996, he achieved board certification with the American College of Veterinary Internal Medicine (ACVIM) and the European College of Veterinary Internal Medicine. 

In 2000, Dr. Steiner received a PhD from Texas A&M University for his work on canine digestive lipases and their use for the diagnosis of gastrointestinal disorders in the dog. In 2012, he was recognized as a Fellow by the American Gastroenterology Association. He currently serves as Professor with the Department of Small Animal Medicine and Surgery and the Department of Veterinary Pathobiology at Texas A&M University. In 2016, Dr. Steiner was named the Dr. Mark Morris Chair in Small Animal Gastroenterology and Nutrition. He also serves as the Director of the Gastrointestinal Laboratory at Texas A&M University and is involved in a wide variety of research in small animal and comparative gastroenterology. He has authored or co-authored more than 280 peer-reviewed articles, 90 book chapters, and 430 research abstracts. He has been invited to present his work at many national and international conferences and provides continuing education lectures for veterinarians across the globe. He has also served several professional organizations in various roles and currently serves as the president of Small Animal Internal Medicine of ACVIM. In 2018, Dr. Steiner received the AVMA Career Achievement Award in Canine Research.


Sina Marsilio, DVM, PhD, DACVIM, DECVIM-CA

Assistant Professor, SMALL ANIMAL Internal medicine 
University of california-Davis

Sina received her veterinary degree from the University of Veterinary Medicine Hanover, Germany in 2004. After graduation she also completed a German doctorate program on feline chronic enteropathies with the Department of Pathology in Hanover, Germany, in 2007. Subsequently, Sina continued her clinical training with an internship in private practice and a residency in Small Animal Internal Medicine at the University of Giessen, Germany and the Royal Veterinary College in London, UK. She received her Diploma of the American College of Veterinary Internal Medicine (ACVIM, SAIM) and of the European College of Veterinary Internal Medicine (ECVIM, CA) in 2014.

After her board certification, she extended her training in small animal gastroenterology and joined the Texas A&M Gastrointestinal Laboratory where she conducted a PhD on the discovery of novel diagnostic biomarkers for feline chronic enteropathies using omics approaches. In August 2019, Sina will join the faculty at UC Davis as an Assistant Professor in Small Animal Internal Medicine with a clinical and research focus on small animal and comparative gastroenterology.
